Energy Management Strategies for Hybrid PV/Diesel Energy Systems: Simulation and Experimental Validation

Abstract

Abstract:Hybrid photovoltaic-diesel systems are becoming more and more attractive for rural electrification in sub-Saharan Africa region. In this paper, some energy management strategies for a photovoltaic-diesel system without battery storage have been theoretically and experimentally studied. The proposed strategies are respectively based on active power control of inverters and controllable loads to ensure security operation for the system and maximize the solar energy penetration. Simulations and experiments have been performed under two different climate conditions and have been applied to an African rural load profile. All the energy management strategies developed have been implemented with the Matlab environment. The obtained results have shown the effectiveness of the proposed strategies to avoid power reserve to the diesel generator, to increase solar energy fraction, to reduce CO 2 emissions, and to ensure the system's frequency and voltage stability.

Fuzzy Logic Based Energy Management For Wind Turbine, Photo Voltaic And Diesel Hybrid System

“…Electrification by grid extension requires a huge investment, which is not feasible in most cases. These facts make the electrification more catastrophic in rural areas [1,2]. These remote areas are widely covered by standalone diesel generators.…”
